Terahertz Scanless Hypertemporal Imaging

open access: yesLaser & Photonics Reviews, 2023
AbstractSince its first demonstration in 1995, terahertz time‐domain imaging has attracted an increasingly growing interest for its ability to reveal spectral fingerprints of materials and probe changes in refractive index and absorption, as well as detect the inner structure of complex objects via time‐of‐flight measurements. Practically, however, its

Critical Factors for In Vivo Measurements of Human Skin by Terahertz Attenuated Total Reflection Spectroscopy

open access: yesSensors, 2020
Attenuated total reflection (ATR) geometry is a suitable choice for in vivo measurements of human skin due to the deep penetration of the field into the sample and since it makes it easy to measure the reference spectrum.

Terahertz single pixel imaging based on a Nipkow disk [PDF]

open access: yes, 2012
We describe a terahertz single pixel imaging system based on a Nipkow disk. Nipkow disks have been used for fast scanning imaging systems since the first experimental television was invented in 1926.

Light-guiding-light-based temporal integration of broadband terahertz pulses in air

open access: yesAPL Photonics, 2023
The next generation of all-optical computation platforms prefers the light-guiding-light (LGL) scheme inside a medium that envisions circuitry-free and rapidly reconfigurable systems powered by dynamic interactions between light beams.

Effect of external magnetic field on terahertz transmission characteristics of electrolyte solution based on microfluidic technology

open access: yesResults in Optics, 2022
In this study, the effect on the terahertz (THz) transmission characteristics was investigated by varying the constant magnetic field time at both ends of the liquid sample (deionized water, CuSO4, CuCl2, (CH3COO) 2Cu, Na2SO4, NaCl, CH3COONa solution ...
